I do hope your scenario plays out but only time will tell. What I can tell is that GE has been looking for efficient printers. Prabhjot Singh mentioned that there are over 300 printers at the company.
There are many optical systems that includes Mazumder, Sciaky, and Arcam but they prove to be inadequate as they don't measure temperature for proper heating. There was a system build by Optomecs 850R that uses an optical system for temperature mapping for closed-loop control but it depends on focus and gives an estimate of temperature analogous to a weather forecast map.
